Families who reside in the west and south, where the housing market was especially hard hit by the recession, were worse off than their peers in the rest of the country.

Making matters worse, income levels also fell during the tumultuous three-year period, with median pre-tax income falling 7.7% as earnings from capital gains all but disappeared.

The loss of income and net worth appears to have impacted savings rates, as the number of Americans who said they saved in the prior year fell from 56.4% in 2007 to 52.0% in 2010 -- the lowest level recorded since the early 1990s.

At the same time, some families were able to escape from debt, as the share of families with debt decreased slightly to 74.9% over the three-year period. Credit card use was down, and the median account balance fell 16.1%.

Meanwhile, families who did report carrying debt showed little change in the degree of indebtedness over the period.

Lower interest rates helped keep debt levels down, but the number of Americans who had fallen more than 60 days behind on debt payments still grew from 7.1% to 10.8% in 2010.
